1The chef explains the difference between baking powder and baking soda.
2She shows a small bowl with baking powder and explains its composition, highlighting the presence of cream of tartar (an acid) and sodium bicarbonate (a base).
3The chef explains that baking powder only needs moisture to activate, unlike baking soda, which needs an acidic ingredient.
4For a recipe using baking powder, there are usually no other acidic ingredients present.
5The chef shows a double chocolate chip cookie recipe as an example of when to use baking soda. The recipe contains cocoa powder and brown sugar, both of which are acidic ingredients.
6She adds baking soda to the bowl containing the cookie ingredients to illustrate how the acidic ingredients and the base (baking soda) react to produce carbon dioxide.
7The chef concludes by stating that this knowledge helps one determine when to use baking powder versus baking soda.
8Other acidic ingredients mentioned include yogurt, buttermilk, and lemon juice.
